Question

1. atomic theory (fill in the blank) give name of scientist and name of model
2. description of particles of matter:
3. first periodic table:
4. discovery of electrons:
5. discovery of the nucleus:

charge of the electron:
discovery of orbitals:
discovery of neutrons:
wave theory:
quantum of energy:
uncertainty principle:

Explanation:

1. First atomic theory of matter was proposed by John Dalton and his model is called the solid - sphere model.
2. Discovery of electrons was by J. J. Thomson and his model is the plum - pudding model.
3. Discovery of the nucleus was by Ernest Rutherford and his model is the nuclear model.
4. Discovery of protons was by Ernest Rutherford (protons were identified in his experiments). Discovery of neutrons was by James Chadwick. The Bohr model (Niels Bohr) described electrons in specific orbits around the nucleus and was an improvement on Rutherford's model for explaining atomic spectra.
5. Discovery of electron orbitals is related to the development of quantum mechanics. Werner Heisenberg's uncertainty principle is a fundamental concept in quantum mechanics. The quantum mechanical model describes electrons as probability clouds in orbitals.

Answer:

1. John Dalton, solid - sphere model
2. J. J. Thomson, plum - pudding model
3. Ernest Rutherford, nuclear model
4. Ernest Rutherford (protons), James Chadwick (neutrons), Bohr model
5. Quantum mechanical model (Werner Heisenberg - uncertainty principle is part of the related theory)
